TO ALL WHOM 4IT MA1,7 CONCRN:

Be it knownthat I, JOSIAH CoP'LEY, Jr., of Allegheny City, in the countyof Allegheny, and State of Penn.`

Sylvania, have invented a new and useful Improvement in Forging-andWelding-Machines; and I do hereby declare the following to be a full andexact description thereof, reference being. had to the accompanyingdraw-4 ings, and letters of reference marl-:ed thereon'.

My invention consists in so constructing a machine for forging andwelding, that its forging and weldingdie`s, while in action,l may beopened and closed,to any desired degree, and their force graduallyincreased or diminished, andadjusted to the work required of them, thewhole being constructed, arranged, and operated substantially ashereinafter described.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

lIIx-the accompanying drawings, which makes part of my specication-Figure l is a perspective view of my improved forging andwelding-machine.

Figure 2 represents a side elevation of the same, with a portion of thebase broken away, for the purpose of showing the treadle, and itsrelation tothe other parts of the machine Figure 3 is a front view ofthc dies and guides, and a section of the parts to which they areattached. Figure4 is 'a top view or plan of the treadle. Figure 5represents a longitudinal section of the arm D, and transverse of thecam used for imparting a reciprocating motion toI said arm.

Figure 6 is a top view of the arm D, and the shifting-guides used forcommunicating the motion of the trcadle to the arm D, without subjectingthe treadle to thejerlring action of said arm.

In the drawings,'A represents the base of the machine, in which isplaced t'ho treadle Z, which is pivoted at the point, and is connectedby the piece u, to the shifting-guides m, which are pivoted on the shaftR, the l upper ends of'said guides being connected by a pin, O, whichpasses through a slotc, in ar'mrD.

To the base, A, is attached the pedestal B, on which are the bearings,6, of the driving-shaft R, on which are secured the driving-pulley and'cam P, which, revolving in the arm- D, gives it a reciprocating motion.The upper end of the arm D is provided with a pin, 8, passing throughthe piece x, which moves freely in slot g of the lever C, which ispivotcd at the pointf to the pedestal B.

To the projections A of the pedestal B and lever C, are secured the diesJ and K, the contiguous 'faces of- Vwhich are made in `form tocorrespond to the work required of them; in the present case beinggrooved for the purpose of welding orswaging rods. On the projection Aof pedestal B are attached guidcsz', t0 prevent the' work from gettingbetween the projections A. f

The operation of my improved forging and welding-machine is as follows:lhedriving-pulley 7L gives a continuous motion to the cam P, giving areciprocating motion to the arm D, which is supported in the directionof the line marked 5, by the action of the spring'S, upon the 4treadleZ, together with the parts connecting it with the arm D. When the arm Dis in this position, the lever C will be in the position represented bythe dotted line 9, and the die Jwill be raised 'sufficiently above thedie Kfor them to receive the work. The treadle l is then pressed down(as represented in iig. 2) by the foot, which, by means oftheconnecting-rod n, and the shafting-guide "m, draws down the arm D,causing it to press the lever C outward, and closing the die J upon thework. The action of the cam-d, communicated through the arm D and leverC, will then repeatedly compress the iron. I The pressures thus producedmay be increased at will by the operator pressing the treadle fartherdown, he at the same time turning and shifting the work so as to producethe desired form and effect. The arm D will not communicate its jerking4motion to the trcadle l, through the shifting-guides fm, since its onlyconnection with tl1ese is' by the pin O, which slips easily in the slote. The treadle Zbeing released, it will be thrown upward bythe spring S,raising lthe arm D, thus bringing it, together' with the lever C, to theposition represented by the dotted lines 5 and 9, thereby lifting thedie J so that the' iron or work may be removed.

Having thus described the nature, construction, and operation of myimprovement, what I claim as of my invention, is-

1. Operating the dies J and K by means of the slottedlever C., arm D,and cam P,oon`structed and arrangedv substantially as herein described,:ind for the purpose set forth.

' 2. The combination ofthe treadle Z, connecting-rod n, andshifting-guides m, when used in coinnection'with the cam P, arm D, andlever C, as herein described, and for the purpose set forth. e 3. Theguides z', when iised in combination with the dios J and K, as hereindescribed and set forth.
